Brewing with rye malt for only the second time, and it seems like it has a blue-ish gray-ish powdery tint to it, looks almost like a mold, but it doesn't really flake off or dust off; it seems integral to the grain. I can't remember seeing this before, but I only used rye last summer for the first time and may have missed it?

A quick Google image search shows some pictures with this stuff on the grain, and some without... the grain smells fine and tastes fine so I think it IS fine.... but any more knowledge on this situation would be appreciated.

BTW it is Canada Malting Rye Malt, from Rebel Brewer, got it shipped in about 2 weeks ago.
